SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 336,504, dated February 16, 1886.

Serial No. 178,927. (ModelJ To all whom it may concern.-

Be it known that I, CARLOS G. WILsoN, a citizen of the United States, residing at Milledgeville, in the county of Baldwin and State of Georgia, have invented certain new and useful Improvements in Spark-Arresters, of which the following is a specification.

My improvements are primarily intended for agricultural or other enginesin which pine or other soft wood is used for fuel. The use of an ordinary wire gauze or netting sparkarrester with such engines causes much trouble by reason of the necessity for frequent cleaning.

My improvements consist of deflecting-plates and receptacles for the sparks and soot,so arranged that all of the heavy particles escaping through the stack will be thrown down in a position convenient for removal or return to the boiler-flue or furnace. To this end I provide inner and outer deflectingplates placed within the hood over the upper end of the stack and arranged to permit the passage of the gases without allowing the heavier particles to escape. Such particles are thrown down into an annular receptacle between the hood and, the top section of the stack, and the latter being made movable said particles may be discharged at pleasure whenever the engine is at rest or when a forced draft is not being created in the stack.

In order that the invention 'may be fully understood, I will proceed to describe it with reference to the accompanying drawing, which represents a vertical section of the upper portion of a stack to which my invention is applied.

1 represents a stack proper, having an enlargement or hood, 2, at its upper end. The two sections of the hood are bolted together, as shown at 3, so as to permit their ready separation, to enable the cleaning or adjustment of the parts of the spark-arrester.

4 is a deflecting plate or cap suspended by rods 5 over the top of the stack 1, and arranged to permit the gases to pass out beyond its edges,while throwing the heavier particles of the products of combustion down into the receptacle 6. A second deflecting-plate, 7, bolted or riveted to the hood 2, is placed slightly above the edge of cap 4:, inclined in opposite direction thereto,and arrests all such lighter or smaller particles as may have passed beyond said cap, and throws them also into the receptacle 6. The rods 5 of the cap 4 are supported by brackets 8, and are screw-threaded on their upper ends, so that they may be clamped by nuts 9 to any desired position of adjustment. The upper section, 10, of the stack is disconnected from the main portion 1, and fixed by cross-bars 11 to a central liftingrod, 12, guided at top and bottom by crossbars 13, fixed to the hood 2 and stack 1, re spectively. A lever, 14, has loose connection with the upper end of the rod 12, is fulcrumed on an arm, 15, bolted to the hood, and provided at its outer end with a pull rod or cord, 16. It will be seen that by lifting the rod 12 by means of lever 14 and cord 16 the section 10 of the stack will be raised to the position indicated in dotted lines, and any soot and sparks which may have accumulated in the receptacle 6 will be discharged down the stack into the front of the boiler-flue. A similar elevation of the section 10, when getting up steam, affords a practically uninterrupted passage np between the two sections of the stack and deflecting-plates, as indicated by the dotted arrow.

Although not here shown,awire gauze or net ting spark-arrester may be placed over the top of the stack in customary fashion, for additional protection upon low sta'cks,where daily cleaning is not a matter of much difficulty.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination, with a smoke stack having an enlargement or hood and a deflecting-plate fixed to said hood and inclined downwardly and inwardly, of a Vertically-adjustable deflecting-cap placed between the top of said stack and said deflecting-plate, the outer part of said cap being inclined downwardly and outwardly, substantially as set forth.

2. In combination withasmoke-stack, hood, and deflecting -plates, a movable section of the stack below said deflecting-plates, substantially as set forth.

3. In combination with the stack 1 and hood 2, deflecting-plates supported in said hood, a having suitable means of operati0n,and guidemovable section, 10, of the stack, a lifting-rod bars for said lifting-rod, substantially as set 10 therefor, and lever and rod or cord for operatforth.

ing said section, substantially as set forth.

4. In combination with the stack 1 and hood 2, deflecting-plates supported in said hood, a movable section of the stack below said plates, a lifting-rod connected with said section and CARLOS G. WILSON.
